#DarkXess :
Thanks for pointing that out, just updated the guide on how to do just that (running multiple mods).

A suggestion. In Arma2 I had a folder called Test into which I put new mods to check if and how they worked with others already added. If I had two new ones I'd put them in one by one into the test folder. The others were in one folder rather than a bunch. After testing I copied the tested mod files to the other group folder. It had already tested fine with them, so it could safely be used. If there were problems I would either ditch the new mod or make a folder to keep it in. I often had two versions of Arma2 with different mod loadouts. The main play one had all the good tested ones together.

I also have read that they can be added in-game, but no info on that. In Arma2 it was called expansions, I think, on the main menu. I could be wrong - anyone??

Hi everyone. I have a problem installing the @mas addon. I used the guide on armaholic. I have the whole nato sf russian spetsnaz weapons pack v1.2 in my main game folder, i have the @mas folder in the main game folder, i tried to put the pbo and design files in the main addon folder. I added the key to the keys folder. I enabled the expansion ingame, but still i get the you are missing the nato sf russian spetsnaz weapons pack v1.2 ingame and then I get kicked out. I also did the -mod=@mas in the set launch options on steam. Still it doesnt work.

Thanks for the prompt reply tom3kb. I didnt know i had to.. what is the weapon pack name. Im trying to get the nato sf russian spetsnaz weapon pack v1.2 installed. what would the -mod string be then? -mod=@mas;??????

Please do not crosspost! Asking the same question in multiple topics is not something we smile about when we see it. Its not needed at all neither!

Just check the folder name of this weapon pack ;) and add it to line.

Thanks again for the quick reply. Ok so it will be something like -mod=@mas;@NatoSfRussianSpetsnazWeaponPackV1.2 ????

Hey, first post here guys. Quite new to Arma and installing mods,I have a couple of questions. So far I have been putting the PBO and Bisign files into the Addons folder right in Arma 3 main directory there, like the video shows him doing. Is that a bad thing? Seems like people are doing it a few different ways, unless I'm simply getting confused. Also does it matter what the keys names are? from massi's mod they ended up both being mas. And lastly, just to clarify how these folders should look, should it go something like this- @Mod name/Addons and Keys and whatnot inside that. some of my folders have a second /@*** , not sure if that will cause problems.
Apologies for the block of texts, I've been feeling very confused about all this stuff Lmao.

Added 13 minutes later:

To give an example of that, one of Massi's folders looks like this. @USMC_A3_v1.1/@mas/addons and keys. for the steam launch parameters, I have @mas put down.

1. Never put put any addons files in main addon folder -> arma 3\addons. You will have problems very fast ;)
2. Mods you always put in @modfolders (pbo and bising files you put in @modname\addons)
3. If you you will make @foldername\@modname\addons game will not see modyfication and will not launch that mod.

Hey, I want to join this heavy modded military sim arma 3 server just wondering if anyone can comment on this post as i extraced a few .rar folders and they didnt extract into folders beginning with @, there were just some loose .pbo files and other stuff. is this okay?﻿

Modedit:Asking the same question in multiple topics makes you look like a spammert and spammerts are sad and we show those the door.
Duplicate post deleted.

No put those .pbo files into a mod format---> @mods/addons
so put the .pbos in the addon folder of the mod folder you create, as those files do nothing by themselves outside of that format. Then add it to you shortcut target line or however you start the game.
